Abstract
A suture sleeve for anchoring the lead body of an implantable medical device includes a tubular body having an exterior surface defining at least one annular, suture-receiving groove. The exterior surface further includes at least one longitudinally extending groove intersecting the at least one annular suture receiving groove and having ends extending longitudinally beyond the at least one suture receiving groove. The interior surface of the tubular body includes a plurality of inwardly extending projections having surfaces adapted to engage the lead body to prevent the sleeve from sliding along the lead body when the lead body is held vertically. The suture sleeve is fabricated of a biocompatible, polymeric material to which has been added color pigment and a radiologically dense material to render the suture sleeve readily visible to the naked eye against surrounding bodily tissue as well as radiologically visible.
